 1. # Check if you are using the correct SSD, X876 supports M.2 NVME ssd only but not sata/ngff SSD, please refer to the picture below: [[File:X876-Supported-SSD.jpg|800px]] 2. # Use the USB 3.0 cable in the box to replace the USB connector to check if the USB connector is faulty.  3. # Check the pogo pins on the X876 board are damaged. 4. # Startup the Raspberry Pi and enter the teminal window, then run the command <code>lspci</code> to check if there is an x876 device? (or send the result to support@geekworm.com) 5. # consider partitioning the SSD, formatting it, etc. refer to to the documentation: [[File:Tutorial Initalize New SSD.pdf]]# Finally, please let us know the store you purchased it from and your order number so we can check if we need to update the firmware for x876.
